Hans Oeschger

Hans Oeschger was a Swiss scientist renowned for his research on past climate change. He pioneered techniques to analyze ice cores from glaciers and ice sheets, which trap ancient air bubbles. By studying these, he unraveled how atmospheric greenhouse gases like carbon dioxide have varied over thousands of years. His work provided crucial evidence of the link between greenhouse gases and climate change, shaping our understanding of Earth's climate history. Oeschger’s contributions helped establish the field of paleoclimatology, offering valuable insights into the natural variability of Earth's climate and informing current climate studies.
